欣古(Xingo)水电站位于巴西圣弗朗西斯科河上的阿拉戈斯州和塞尔日培州交界处,总装机容量为5000MW,是巴西的第二大水电站。该电站有以下突出特点:(1)工程难度小。由于大坝(长为850m,高为140m 的面板堆石坝)是建在一个由圣弗朗西斯科河冲蚀成的干枯的峡谷里,因而在这修建水库相当容易。(2)能够保持生态平衡。由于不淹没良田和森林,所以对周围的植物和动物几乎不造成 The Xingo hydroelectric power station is located at the junction of Alagoas and Seljampysca on the São Francisco River in Brazil with a total installed capacity of 5,000MW, making it Brazil’s second largest hydropower station. The power station has the following salient features: (1) project difficulty is small. Due to the dam (850m long, 140m high CFRD) built in a dry canyon eroded by the San Francisco River, it is fairly easy to build a reservoir here. (2) to maintain ecological balance. Since there is no flooding of fertile fields and forests, there is almost no damage to surrounding plants and animals
